研究目的在于寻求健康人在正中与非正中咬合运动时的振动波型特点。将一适当的振动传感器依次置于额部、眶下部及乳突部,记录在记忆示波器上所显示的波型。根据65例的分析,得出如下的结果:(1)波型正常者52例,它仅含有一个有规则的开口波与闭合波,不正常者13例,波型不规则,常出现有额外或干扰波。性别与年龄无明显的差异;(2)咬合周期为(?)=0.34秒,S=0.10;(3)开口波与前后闭合波的时间对比关系,个体间不同,但个体本身多少是恒定的;(4)非正中咬合运动幅度在(牙合)面磨耗重者较大。
The purpose of this study is to find out the characteristics of the vibrational modes of healthy people during occlusal movement between the center and the non-center. Place an appropriate vibration sensor on the frontal, orbital and mastoid and record the waveform displayed on the memory oscilloscope. According to the analysis of 65 cases, the following results were obtained: (1) 52 cases of normal wave type, it contains only a regular open wave and closed wave, abnormal in 13 cases, wave irregular, often with extra Or interfere with the wave. There was no significant difference between sex and age. (2) Occlusal cycle was (?) = 0.34 second and S = 0.10. (3) The time contrast of open wave and closed wave was different between individuals, but the individual itself was more or less constant ; (4) non-positive occlusal movement in the (occlusal) face wear heavier.
